Featuring a gold ionized lens with Lumalens color technology, the D1 OTG from Dragon Alliance arrives in a "Classic Grey" colorway. Compatible with helmets and prescription glasses, the performance goggles optimize depth perception and contrast - while an anti-fog coating and active ventilation ensure clarity at all times. Outfitted with triple-density face foam and a hypoallergenic fleece lining, the D1 OTG is complete with a grey strap and knit lettering along the temples.
